Title : Modelling height-diameter relationship for Chir pine trees Material Type: printed text Authors: SHARMA, R.P., Author Publication Date: 2009 Article on page: 3-9 p Languages : English (eng) Keywords: Chir pine height-diameter models model evaluation stand attributes Abstract: Tree height-diameter relationship can be used as an important input component in growth
and yield models, and description of stand dynamics. This study aims at establishing
robust height-diameter models for Chir pine (Pinus roxburghii) trees using regression
techniques. Among the twelve non-linear models fitted to height-diameter data from twentythree Chir pine stands in Parbat and Shyangja districts, Hossfeld’s model accounted for
the largest proportion of height variations (R2
adj
= 86%), and appeared to be biologically
most realistic. This model can be applied to similar stand conditions from where study
data were procured.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=10

Title : Above-ground carbon stock assessment in different forest types of Nepal Material Type: printed text Authors: S.K. Baral, Author ; R. Malla, Author ; S. Ranabhat, Author Publication Date: 2009 Article on page: 10-14 p Languages : English (eng) Keywords: Above-ground biomass carbon forest types Nepal Abstract: This study assessed the above-ground carbon stock in the five major forest types,
representing two physiographic regions and four districts of Nepal. Altogether, 116 circular
sample plots were laid out systematically in different forests types to inventory the forest.
Total above-ground biomass was derived with allometric equations. Results indicated
variation in age of the stand (18-75 years), above-ground carbon stock per hectare (34.30-
97.86 dry wt. ton ha-1) and rate of carbon sequestration (1.30-3.21 t ha-1yr-1), according to
different forest types. The rate of carbon sequestration by different forest types depended
on the growing nature of the forest stands. Tropical riverine and Alnus nepalensis forest
types demonstrated the highest carbon sequestration rates in Nepal.Link for e-copy: http://lib.frtc.gov.np/elibrary/?r=11

Title : Change assessment of forest cover in Ghodaghodi lake area in Kailali district of Nepal Material Type: printed text Authors: S. Khanal, Author Publication Date: 2009 Article on page: 15-19 p Languages : English (eng) Keywords: Change detection Forest cover Ghodaghodi lake Landsat Abstract: Ghodaghodi Lake in Far-West Nepal has been listed as a Ramsar Site due to its significance as a habitat for several endangered species of flora and fauna. The wetland and its surrounding area is facing deforestation, forest degradation and encroachment. In this case study, unsupervised and finally supervised classification of multi-temporal Landsat imagery covering the wetland area was applied. A post-classification comparison approach was used to derive forest cover change maps. The results depicted the loss of forest cover over a thirty- one year period, in three time slices. The highest rate of loss was observed in the 1990 to1999 time slice. Link for e-copy: http://lib.frtc.gov.np/elibrary/pages/view.php?ref=51&k=

Title : Harvesting methods of Cinnamomum tamala leaves in private land: a case study from Udayapur district, Nepa Material Type: printed text Authors: D. Lamichhane, Author ; N.K. Karna, Author Publication Date: 2009 Article on page: 20-24 p Languages : English (eng) Keywords: Fresh weight harvesting private land Tejpat Abstract: Tejpat (Cinnamomum tamala) leaf is commercially one of the important non-timber forest products of Nepal. This paper attempts to elaborate and analyze the harvesting methods and techniques of Tejpat grown by the farmers in their private land. The study was conducted in the villages of Udayapur district where Tejpat was widely cultivated and harvested for income generation and trading purposes. Almost all farmers with private land had planted Tejpat. Complete lopping of leaves once a year was the exclusive practice for harvesting. The collection period for leaf was from Ashoj (October) to Magh (February) but the period for bark varied greatly, i.e. from Kartik to Poush (November to January) and Baisakh / Jestha (May / June). Bark collection was done only from old, dying, diseased and low leaf producing trees. Average number of trees per household ranged from 10 to 155. The mean diameter at breast height (DBH) of the trees was 39.58 cm. There was high positive correlation between the DBH and fresh weight of leaf. Fitting of linear regression of fresh weight of leaf with DBH proved that the relationship was statistically significant at 5% level of significance. The minimum age and size of trees for leaf harvesting were found to be five years and 16.18 cm, respectively. Link for e-copy: http://lib.frtc.gov.np/elibrary/pages/view.php?ref=52&k=

Title : Modelling the growth of Shorea robusta using growth ring measurements Material Type: printed text Authors: P. Sapkota, Author ; H. Meilby, Author Publication Date: 2009 Article on page: 25-32 p Languages : English (eng) Keywords: Climate change community forestry diameter growth models effect of rainfall ring measurements Abstract: This paper presents distance-independent diameter growth models for Sal (Shorea robusta Gaertn. f.) in Kankali Community Forest, Chainpur VDC, Chitwan. As the basis for modelling, stem discs were cut 0.3 m above-ground for a sample of 80 trees that had recently been felled. Growth rings were measured along four radii and, except for the outer part of a few discs originating from old trees, individual growth rings could be distinguished without major difficulty. Supplementary data were gathered as a basis for preparing models relating [i] diameter under bark to diameter on bark and [ii] diameter 0.3 m above-ground to diameter 1.3 m above-ground. Based on these data, auxiliary models were developed and used to convert growth ring measurements into diameter increment at breast height. The mean diameter increment was 0.87 cm/year (n = 1514) and the standard deviation was 0.33 cm/year. The relationships between diameter increment and current diameter, stem age, growth in previous years, rainfall and temperature were modelled. Four different models were presented. Rainfall during the growth season, particularly the months of May-July, proved to influence growth considerably and suggests a scope for dendroclimatological studies in Sal.

Title : Value chain analysis of non-timber forest products in Baglung district, Nepal Material Type: printed text Authors: A. Paudel, Author ; SUBEDI, B.P., Author ; S. Gyawali, Author ; G. K. Thapa, Author ; M.B. Sharma, Author Publication Date: 2009 Article on page: 33-41 p Languages : English (eng) Keywords: Key words: Business solution constraints non-timber forest products opportunities value chain Abstract: This study was carried out in five Village Development Committees of Baglung district, Nepal. The main objective was to assess the constraints and opportunities to run the non-timber forest products based enterprises, and to design business solutions to make their value chains more efficient and competitive with the best utilization of the available resources. Primary data were collected through group discussions, key informants interview, informal meetings and direct observations, using open-ended questionnaires and checklists. Similarly, secondary data were gathered from reports and records of community forest user groups, District Forest Office and other organizations. The data were analyzed using qualitative and quantitative tools. The identified major constraints concerning the selected value chains are: absence of detailed resource inventory; inadequate knowledge and skills with local people about modern technology and product quality parameters, local resource management policy and sustainable resource harvesting; insufficient finance with local processors; lack of sufficient information about market; and poor infrastructure development. In addition, the study also identified a number of opportunities such as the resource potential and monetary benefits to the local people; financial access through community forest user groups' fund and financial institutions; growing market demand for quality products; involvement of service providers in forest resource management; and supportive policy for employment generation from locally available natural resources. This paper has suggested some business solutions for the effective value chain of selected products. Link for e-copy: http://lib.frtc.gov.np/elibrary/pages/view.php?ref=54&k=
